This is Ol Mick’s bag. As you know he is very much an alcoholic, so the tequila in his bag is a must. The blender and blending cup is just in case he gets sick of plain tequila and wants to make a mixed drink.
He has his black folder which is a journal for crime investigations and his green journal which is a day to day/event to event kind of deal. Last he has his wallet and keys. The wallet is an essential artifact in his bag because it has his ID and money to purchase more alcohol. The keys he rarely gets to use because he is usually to drunk to drive.
